| 中文摘要 | 將五週齡之蛋雞255隻分成兩批17組,每組各15隻,其中第一批有7組,第二批10組,每批除一組為陰性對照組之外,其餘各組均個注射一種不同廠牌的產蛋下降症(EDS)毒疫苗,第一批免疫分別在二、四、八週後採血,第二批免疫後,分別在三、六、九、十二週後採血,以檢測EDS血球凝集抑制(HI)抗體力價,結果發現各種不同廠牌EDS死毒疫苗之抗體力價優劣差異頗大,因此慎選優良品質之EDS死毒疫苗是做好EDS免疫獲得高抗體的垂要關鍵。 另統計本研究室1987年至1993年間之5207隻種雞和蛋雞為主之EDS抗體,發現其EDS HI抗體力價主要(55%)介於1:40∼1:1280間,大部份雞隻的EDS HI抗體均超過具免疫保護之力價(1:20),此顯示台灣雞隻EDS免疫便為具體確實,也具體說明谷何以近年來台灣EDS少有發生之原因。 |
| 英文摘要 | Two trials on the evaluation of commercial egg-drop syndrome (EDS) oil emulsion inactivated vaccine (OEV) were done in 255 5-week-old leghorn pullets. The birds were divided into 2 batches of 17 groups, 15 birds per group. Each of the 7groups in the first batch of the trial were immunized with one of the variety of commercial EDS OEV, then bled at 2,4 and 8 weeks postvaccination in 1992. Each of the 10 groups in the 2nd batch of the trial were immunized with one of the variety of commercial EDS OEV, then bled at 3, 6, 9 and 12 weeks postivaccination in 1994. All the sera collected were subjected to EDS hemagglutination-inhibition (HI) test. The HI antibody response to different company's EOS OEV product in the first evaluation was found moderate, differeuce but greatly differed in the second evaluation. Selection of a good EDS OEV is necessary to get a good immunization HI antibody response. A total of 5207 serum samples of breeders or layers collected by this laboratory during 1987 to 1993 for testing against EDS HI antibody showed that 55% of the EDS HI antibody titer were between 1:40 to 1:1280. Most of the HI antibody titer were more than the protective titer (1:20 or even lower). The geometric titer of the EDS HI antibody increase year by year except 1991. Since 1987, EDS immunization has been extensively extensively practied Taiwan. This could be a good explanation on why EDS rarely occurred in Taiwan nowadays. |
